Application April 29, 1932. Serial No. 608,235 'i olaim. (o1. zip-14f Itis the object of this. invention to provide a novel and improvedsectional silo clip for holding the sections of a sectional silotogether with one section resting upon another section.

Although this clip isadapted for use in connection with sectional silosof different types, it is particularly adapted for use in connectionwith the particular sectional silo disclosed in the United Statesapplication for patent, filed in the name of Peter Rutten, Serial Number539,812 on May 25, 1931, entitled Portable silo or the like, and whichbecame Patent No. 1,904,932, April 18, 1933. I

The objects and advantages of the present invention will more fullyappear from the following description, made in'connection with theaccompanying drawing, wherein like reference characters refer to thesame or similar parts throughout the various views, and in which,

' Fig-1 is a view in front elevation showing two sections of a sectionalsilo, the sections of which are interconnected and held together bymeans of clips embodying the present invention;

Fig. 2 is a perspective view illustrating a pre- 5 ferred type of clipthat may be used;

Fig. 3 is a view in end elevation of the clip shown in Fig. 2, asapplied to one section of a silo; Fig. 4 is a vertical section taken onthe line 4- 1 of Fig. 3, as indicated by the arrows; and

Fig. 5, Fig. 6, Fig. '7 and Fig. 8 are perspective views of other typesof clips embodying the invention that may be substituted for thepreferred .type of clip, shown in Figs. 1, 2, 3 and 4. r

Referring to the drawing, there is illustrated in Fig. 1, two sections Aand B of a sectional silo embodying the invention of Peter Rutten aboveidentified. Each section A and B comprises an elongated flexible stripconstructed somewhat in the manner of flexible snow fencing material 3and including a multiplicity of parallel staves or slats 8, each securedby means of staples 9 or other suitable attachment means to encirclingwires 10. The ends of these elongated strips are connected to the sidesof door panels 11 within which doors 12 are mounted. Chute sections 13may be applied to the sections A and B if desired, as the section 13 isillustrated as being applied to the section B. The sections A and B willbe laid out to take substantially circular or ringshape as illustratedand, if desired, encircling rods '14 connected at their ends to blocks15 may be used for strengthening and bracing the sections A and B. Inerecting silos of the type illustrated, it is customary to first set upthe lower section A L whereupon in accordance with the invention, a

tween the different silo sections.

strip of padding P, such as felt, is applied on the upper edge of thelower section A and one or more upper sections Bare positioned above thelower section A and the lower edge of each upper section, such as thesection B, is applied to rest on the padding Plying on the upper edge ofthe section immediately below the same, i. e. the section B is supportedon the section A, and if a third section were added, this section wouldbe supported on the section B. To interconnect and, retain the sectionsof the silo together, clips such as the clips C may be used.

Each clip 0, as best illustrated in Figs. 2 and 3, includes a centralweb 16 within which an elongated opening 22 is formed, a pair ofparallel down turned, spaced flanges ll'joining the edges of the web 16,and a pair of upturned, parallel spaced flanges 18 struck from theflanges 17 and joining the edges of the web 16. To conserve material andat the same time to give the downturned flanges 1'7 sufficient strength,the flanges 18 are rounded at their upper ends. The spacing between thetwo flanges l7 and the two flanges 18 is just sufficient to permitreception of the staves 8 of the sections of the silo and the padding Pbetween the same.

After the lower section A of the silo'has been erected and the padding Pis applied to the upper edge of the same, a plurality of the clips C areapplied to the upper edge of the lower section A so that the upper endsof certain of the staves of the lower sections together with portions ofpadding P will be received between the flanges 1'7. The web 16 of eachclip is forced well down into the padding P and due to the resilientnature of the padding and the provision of the opening 22, the paddingwill bulge up through the opening 22 and at the edges of'web 16 so'thatthe thickness of the padding at the point where the clip is em beddedtherein will be no greater than the thickness of the padding at otherpoints, as illustrated in Fig. 4. The upper section B will then beerected on the lower section A to rest on the padding P and certainstaves of the upper section adjacent their lower ends will be disposedbetween the flanges 18 of the clips. 18 will prevent lateral movement ofone section relative to the other section and thus the sections of thesilo will retain their position without further securing of one sectionto another. The

The flanges 1'7 and padding P within which the webs 16 of the clips areembedded causes a tight joint to be made be- The clips may be readilyslipped in position during erection of the silo and when the silo isbeing taken down,

no difflculty is experienced in removing one section from the other byreason of the use of the clips C.

In Fig. 5, a second type of clip D is illustrated, which can besubstituted for the clip C if desired. Thee lip D is very similar to theclip C with the exception that it is longer than the clip C and insteadof having only one pair of upturned flanges, and one opening in thecentral web, the clip D is provided with two pair of upturned flangesand two openings in the central web.

In Fig. 6, a still different type of clip E is shown which also may beused in place of the clip C. This clip E includes a central web 19having an opening 23 therein, a pair of spaced parallel rectangulardownturned flanges 20 joining the edges of web 19 adjacent one end ofthe same and a pair of spaced parallel upturned flanges 21 joining theedges of the web 19 adjacent the other end of the same.

In Fig. '7, another 'slightly'diiferen't type of clip 15 is shown, andthisclip is similar to the clip E with the exception that'two pair oflongitudinally spaced downturned flanges are provided and one pair ofupturned flanges'are provided longitudinally intermediate the dowhturnedflanges, while two openings areprovided in the central web of the clip.

In Fig. 8, yet another type of clip G is shown. This clip 'isconsiderably longer than the other clips illustrated, but itis generallysimilar in construction to the clips E and F. The clip G in" cludes aplurality of pairs of downturned flanges spaced longitudinally from eachother and a number of pairs of upturned flanges spaced longitudinallyfrom each other. The central web of clip G is provided with a pluralityof openings.

changes may be made in the form, details, ar-

rangement and proportions of the clip without departure from the scopeof the present invention, and it will also be understood that the clipmay be used in connection with various types or" sectional silos andother kindred sectional structures. The invention consists in the mattershownand described and set forth in the appended claim.

What isclaimed is:

A sectional silo comprising an upper circular section, a lower circularsection, a strip of padding overlying the upper edge'of the lowersection and upon which the lower edge of the upper section rests, and aplurality of clips for securing said upper and lower sections together,each clip including a central web interposed transversely between saidsections and apertured to receive the strip of padding material topermit embedment of'the web therein without increasing the thickness ofthe strip of padding material, each clip also including down-turnedflanges spaced from each other, joining the edges of said web andembracing said strip of padding material and said lower section, andupturned flanges spacedifrom each other joining the edges of saidwebandembracing said upper section.
